Cleaning a carburettor from an outboard motor
HTML-код
- Опубликовано: 19 май 2015
- In this video I clean the carburettor from a Yamaha 15HP two stroke motor. This is a relatively simple process that only needs common hand tools. Many problems with outboard motors are caused by dirty or water in the carburettor and can be fixed completely by following this process. The video starts with removing the carburettor from the outboard then disassembling it. Once sprayed with a bit of carburettor cleaner and compressed air it is put back together, ready for action.

These are some of the best videos that I've seen. I'm a little embarrassed to say that I just sit and watch these for fun. I have an outboard that works perfectly right now but for some reason I'm fascinated by your knowledge and ability to explain/instruct. Well done!
Thanks mate, glad you've been enjoying the vids. :)
quebow03 Smart to do just in case your ever up shits creek without a paddle you swing into action.
No need to be embarrassed, stu is a great teacher. Literally no junk other then education. I’ve most of his video and learned heaps. Wish i discovered this channel prior to dumping my operational 30hp (was fuel supply issue)
Embarrassed?-
Now if you told me you dig the simpsons or some mind rot, then maybe be embarrassed...but this is actually educational, practical and interesting 😉
@@DangarMarine Agree with gent above! Thanks for posting these!
Thanks so much for the video. Hadn’t started the boat for 6 months and when I did I could only run the motor with choke on otherwise it cut out. After some diagnostics I determined it must be clogged injectors in the carbies. Best quote I could get to clean Yamaha V4 115 was $350-400. After watching your video I had the confidence to give it a go myself. Paid $9 for a can of carbie cleaner and went very slow and methodically with lots of photos and it still only took me 2.5 hours to do all four carbs from start to finish. Injectors in two of the four were very blocked. All cleaned out and put back together with no difficulties. Runs beautifully again. Thanks so much Stu 👍👍
You're welcome Dan. Glad to hear you got your boat up and running. There is nothing more satisfying than getting out on the water and knowing you made it happen. :)
Just wanted to say thank you again for this video. I got the carbs cleaned up and it's a night and day difference in how the boat runs.
Hi Hise, yes, dirty caburettors are one of the most common problems with outboards and cleaning them up can make a huge difference to how they run. Glad yours is going nicely now. :)
Stu you have saved me so much heartache in the short time I’ve discovered your videos. Thanks so much for taking the time to make these, an invaluable resource, greatly appreciated.
Thank you for posting. Helped me restore 2 carburetors for my 2 stroke outboard! Runs like a champ now. There's something about cleaning out a carburetor that just makes you feel good!
rockz12 Glad the vid helped. Getting a carb nice and clean sure is satisfying! :)
This is, without doubt, among the best instructional videos I've seen. As a Navy air mechanic on most things from Whirlwind Mk.3 to Sea-King Mk.1, and a motorcycle fiend of some note, I'm OK around a tool kit, but you've given me the confidence to hold meaningful communion with my Yammy 28 outboard. Thankyou so very much. Bob.
Great tutorial, great presentation giving us amateurs confidence to give it a try. Thanks
Thanks for the video. I followed you step by step and my motor is running great. That’s the third of your videos that I have used. Great job!
Another video that will definitely help the DIY marine enthusiast. Looking forward to the syncing video.
Thanks for this great video. It gave me the confidence to take apart my carb to get the outboard running again when we were anchored in an isolated offshore island.
You're welcome mate, glad it helped. So many outboard problems are just dirt or water in the carburettors so getting comfortable with cleaning them will serve you well over the years.
This tutorial saved me hundreds...thanks mate ! My Merchatsu 30 thanks you too I used the SCA Throttle body and carb cleaner....heavy duty stuff ..use in moderation indeed
You're welcome. Glad the video helped you. :)
I have watched over a dozen different carburetor videos and yours is the best of the bunch.
Thanks mate!
Thanks for great educational videos. I can say that the years of experience you must have make my life easier when it comes to working on my boat. Thanks!-Chris
+Chris Ward Thanks Chris, you're most welcome. I'm glad the videos helped you. :)
Best marine how to site on RUclips! Thanks
I take apart, clean, service, and put back together fishing reels for a hobby. I think I could do this, with your fine tutorial. Thank you for sharing this. If I could afford to fly to Australia and apprentice with you I'd do it in a heartbeat. Keep up the awesome videos, excellent camera work, and calming demeanor.
Thanks Eric, glad you like the videos. :)
Once again great information - very detailed. Thanks for taking the time to film and upload the videos.
+000Troy000 L My pleasure. Hope it helps.:)
Hi Stu. Thanks for the great information on carby cleaning. I have a Yamaha 85 hp OB that was not reving above 3800 and slow to pull away with full throttle. Checking the spark plugs found #3 cylinder not getting much if any fuel air mixture. Disassembled all 3 carbs and found #3 carb had blocked jets. Boat had not been used for 3 years. Now enjoying Moreton Bay Boating again. Cheers Andy.
+747SP727 Nice one Andy! Glad to hear you got it running again. I did my SCUBA ticket up on Moreton Bay, lovely place. :)
Awesome video which has given me the confidence to try this on my outboards carb. Keep the videos coming please.
This video is greatly appreciated. Thanks from Lake Michigan
Great video. I’ve only been messing with outboards and boats for the past year or so and resources for my particular outboards are hard to come by (1977 & 78 models), so I’ve been relying on your videos and a couple others here and there for technical advice because I can’t afford shop rates for repairs. You’ve been incredibly helpful along the way so thanks! Cheers from Georgia, u.s.
Great! IN particular, your simple hand-drawn tip of the needle valve is a brilliant difference between other RUclips mechanics who try to describe what is happening with wobblecam. And every time you use a cloth or your hand to highlight some tiny part is very special. You are a great presenter. Cheers
Thanks Mike, glad you enjoyed the vid. :)
just watched your video on cleaning a carb ( gave it a thumbs up ) , Thanks for walking me through it this past week, most greatful ! As soon i can get a chance i will be cleaning my carb THANKS AGAIN
I now have a TV in my garage and the only channel running is Dangar Marine. The story of your trawler is awesome as well.
I want to thank you for this excellent video. I watched it two or three times and then successfully disassembled the carb on my Honda 9.9, cleaned it, put it back together, and vroooom! Engine runs great. My baseball cap is off to you. Thanks.
Nice one Harvey, glad to hear you got it fixed up. :)
Stu, your videos are perfect. Plenty of details, with just enough humor. I Cleaned out two Yamaha carbs this evening with confidence gained from this video. Thanks mate.
You're welcome John, glad they helped you. :)
You're welcome John, glad they helped you. :)

Bless u for not saying yammie-or carby
Oh god- bless you ....
Big THANKS for your video and information it has been most detailed, looking
forward to stripping mine down 'both' on my 1980s mariner 40hp, just finished
making outboard stand similar to yours keep up the good work. Joy to watch.
mikezoomy Thanks Mike! Glad the videos helped you out. Enjoy your time on the water. :)
Thank you, thank you, thank you.
I love your videos and have learnt so much from them too. You are an excellent teacher. thank you so much.
Love from South Africa.
Well done and put together. Many thanks. Amazed at how well you handle tiny parts with those gloves on!
Thanks Mike, hope the video helps you. :)
one of the best carb videos on You Tube. Thanks.
Thanks to your vids , i have gone thru a 1971 Johnson 60 that was being discarded and for less then 200 dollars have it , not only running but runs like new and has great compression. Thanks
Nice work! Always great to hear of another old motor back up and running. :)
I be done this only a few times but YES IT WAS VALUABLE ! Thx! The take a photo first, is a beauty haha
You saved me hundreds on a mechanic doing my lower unit for sure . Thank you very much from Steve in New York, USA
Happy to help Steve.
@@DangarMarine I even did it without thinking juice. LMFAO 😂😂. I have it up. August 1st will be 4 years. I'm 60 can live the rest of life without it. Caused me to many problems.
@@DangarMarine happen to have a complete trim package for my motor ?? It's a 1993 Evinrude 48 SPL model# E48ESLETE
Great job explaining the process!!! thanks!
Glad it was helpful!
Thank you for another great video. I have an old 1987 SeaRay 135hp that won't draw fuel into the carb. After watching the video, I am thinking that the float might be stuck. The fuel pump has been rebuilt and everything else seems to be working. I really appreciate your knowledge and detail. Great website also, I visit often, Cheers!
I enjoyed your videos. They are explained well and are very informative for the DIY people.
These episodes are timeless > Cheers
You have amazing knowledge of boats I love the way you explain to the novice, I ve now seen all your videos there fantastic, many thanks a thumbs up from me Terence in the United Kingdom
Thank you very much! Glad you've been enjoying the vids.
Thanks again for another very helpful vid ,I’ve had a lot of problems with my 35 Johnson an every vid help it run that little bit better
You're welcome mate. :)
Apparently Aussies are the only ones that know how to fix outboards lol. Every video I click. I’m not complaining though. Very nice video.
These types of videos are great, I’ve learned a lot, virtual schooling really isn’t a new thing.
I've seen alot of marine type videos and danger explains it best IMO. Think I've watch just about all of them!!
Great video! Gave me confidence to rebuild my Mariner 40
Thanks!
You're welcome, good luck with the rebuild!
Quite simply Stu, HIGH 5 Brother. You make each aspect of what you share easy to understand and the explanation you give as you go through each video is just that much more information that we all should have if we are attempting to fix or even just maintain our own equipment. Only recently found your channel and am now subscribed and Sharing as much as possible. Thank You Sir!
Thanks mate, glad you've been enjoying the vids and always appreciate people spreading the word. :)
Thank you very much for your video. I will clean the carburator on my outboard engine based on your instructions. Like your video and way you explain the process. Thank you sir.
Thanks mate, good luck with the job. :)
Thank you Dangar Marine for this video. My boat recently broke down on the water and we had to be towed. The fuel bulb was cracked so we bypassed the bulb straight to the engine. We were able to get her started, but as we ran the boat it started losing power in spurts eventually died on us. We were able to get it started 1 more time in which smoke started shooting out of the back, we shut it down and were unable to start it after that. We had to be towed to the docks. After watching your video, I cleaned the carburetors and the engine started. When I cleaned the carbs they were full of fuel and oil mixture which seemed to contain more oil than fuel. Other than that they were pretty clean i side. After putting the carbs back on and starting the engine, unfortunately there is still allot of smoke coming out of the back. I ran the engine for a couple of minutes, off and on for a total of around 4-6 minutes. I have a 1996 Johnson 2 stroke outboard with a seperate VRO Oil tank. Do you know what the problem may be that is causing all the smoke. Your help would be greatly appreciated.
Thanks
Sounds like the VRO is adding way too much oil. It could be jammed and just free flowing. I don't know that much about those VRO pumps but this video does go through taking one apart to clean it. ruclips.net/video/E-2DznvgXSY/видео.html
Great video! Was able to remove and clean carb from Nissan 8 hp 2 broke. Replaced and engine runs great! Thanks!!!
Nice work! Glad the video helped. :)
Excellant explanation on all his videos.
i cleaned my carby and my motar ran alot better, i watched this video after i cleaned it and noticed i did not know there was an idle jet under the rubber cap, i did not clean it, so even though i had already done it i learned something by watching you and now have to clean it again :) hah
Excellent! I've got two motors waiting for a carb cleaning. Happy to try myself before paying to have the work done.
Good luck!
Thanks HEAPS Stu.
I really enjoy your videos and the way you present them.
Yamaha 30hp has been making a chirp and then stall. Thought, "I had better revisit some "Dangar Vids", Stu will have a fix"!!!
Hope all is well. Thanks again for all the Info.
Awesome video. Thanks for sharing.
You’re welcome. :)
Thankyou for such a superb practical introduction to self servicing your outboard carburettor.(idle jets blocked )
Watched twice took notes prepared tools time and place, removed, stripped carb clean applied, aerosol can blow through, evidence of water, sludge and build up of crud on butterfly valve jets and fuel bowl) all removed jets cleared reassemble and fit tank test.
Satis
2011 - 15 HP Mariner four stroke , 14 hours only from new, E10 fuel used by previous owner 2 years not used, sorted... first pull fired up tickover perfect. Way to go.
Total task time : start - test 3.5 hours . so pleased with the advice, I now know how to keep this £2865.00 engine in peak condition. R. (just watched 3rd time we did good!) l'sailor 77 years ! great lecture.
You're welcome Roger, great to hear the video helped you.
Incredibly helpful video and awesome channel! Thanks! I wish someone would make videos with this level of quality and detail for my motor (1983 Evinrude V4), but with this as a general guideline and the shop manual on hand, I think I can do it. Thanks!
Oh, and I second the request for a synching video! :-)
They are all relatively similar, certainly the principles are the same even if the carb design is slightly different. Synching video on the way! :)
Stu, I love your videos and the way you present them. You are an excellent mechanic/presenter, full of knowledge. You remind me so much of the Diver Dan character out of the original, "Sea Change " series, calm and very articulate. I purchased a set of gunsmithing screwdrivers from Brownells in the USA for working on carbs. They have a wide range of width and thickness, ideal for those awkward screw heads you come across. You live in a beautiful part of Oz. Keep up the great work.
Thanks mate, good tip about the screwdrivers.
Love the channel very informative. I work for the US Coast Guard and i had a 50hp honda that i couldn't get the carburetor clean by taking it apart and cleaning it. I even had it cleaned 2 times with ultra sonic cleaner and that didn't work. So i found where someone boiled the carb in lemon juice. Works every time. You can just take the bowl and float it of and then put it in a pot of lemon juice and boil it for 30 min. Then wash the holes out with cleaner. It doesn't even ruin rubber or gaskets.
Interesting tip Andrew, I'll have to give it a try one day.
Very instructive. I'm heading to the one with the fuel pump now.
+cellardoor70 Thanks mate, glad you enjoyed. I'm planning to do a video on diagnosing fuel pumps very soon. Stay tuned!
Great video, will be doing this myself now, saved me $$ for sure! Thank you.
Glad it helped
Thanks for taking time and post this video !
I learned a lot from your video !
You're welcome, glad it helped. :)
Perfect timing, although my engine has sat for like 15 years I'll try this to see if it does something!
Can't go wrong fixing the free stuff first
I do small engine repair you need a battery powered drill you can chuck up a 1/4 inch extension makes disassembly lots easier and you can set the chuck so it will not over tighten the screws and great vid you are really good
Yeah, a good cordless drill can certainly make things faster, particularly with those magnetic extensions for fast changing of bits.
Thank you. Good work, well done.
Bravo!! you're a good a teacher I am looking forward to see your other videos, well done!
I wish I could like this video twice!
Hi Stu! Great video! Easy to follow. Thank a tons from Copenhagen
This video was great!! Thanks for posting it.....
+Dan Krych Thanks Dan, glad you liked it. :)
Great video. You’re pretty thorough!
Thanks mate!
Very educational, thanks very much. Takes a lot of mystery out of it.
Thanks mate, glad it helped you. :)
outstanding...........best video so far on this topic!
Thanks mate!
Yet another excellent video. Thanks Stu.
You're welcome Bob. :)
Thanks, you do a great job with your videos.
Another brilliant video, Stu. I'm working my way through the lot and am learning with every one. I recently purchased a nice old Evinrude 18hp from (1968 vintage that's been in a shed for thirty years unused- yikes...). I'm going to rely on all your vids to go through carb, fuel tank, line and pump, water pump, gear case and block before I even try to fire it up. So far all I know is that it turns over when the flywheel is rotated, so that's a win...I will let you know how it goes.
Keep up the terrific work!
Thanks mate, glad the videos are helping you. Good lick with the Evinrude, great news that it turns over freely. :)
Being a sixties vintage outboard I'm going to be into checking points, condensers, and magneto....Don't suppose you've got any how-to vids on anything so ancient? 🤔
I am about to attempt this I got an old Salva 30hp that is struggling to start and runs horrible when it eventually starts.I am following your logical steps to fixing it. First the fuel pump then fins and carb clean as a last resort. Wish me luck I'm going in. Brilliant video you are such a cool guy long may your lum reek.
A dirty carburettor is a very common cause of that type of problem. Nothing to fear, just go slowly and take photos. :)
Many years ago I had a Selva 25 with similar problems. In the end I took the power head off the leg and the exhaust was completely blocked with carbon. Hope this helps if you haven't sorted it. Cheers Barry
Appreciate your videos
I want to say cheers man!!!! thank you so much bro, growing up without a DAD but bieng a chippie I have always been a little embarrassed about my lack of MOTOR SKILLS. Just fin watching only a few of your vids mate you NAILED IT. You are really good at what you do, mechanic wise but in front of Camera. Mate this is something big for you as I feel READY to attack my outboard. Thanks again. Pete. Near Brissy
Thanks Pete, glad you've been enjoying the vids. :)
Thanks Stu for your video great mate well done.
You're welcome!
Love your pragmatic videos and am hopeful your might have some advice for a persistent lean idle challenge with a 2003 Yamaha F90TLRC. Based on my research it appears this model as well as Mercury 4 stroke 90 hp of this vintage had numerous complaints of lean idle issues in the warranty period. Idle jet, fine as frogs hair, on a regular basis gets obstructed with "snot." I added water separator, filtration after fuel pump and regular use of Mercury gasoline additive. Carbs have been synchronized and idle mixture adjusted. Even when clean and idle mixture is adjusted, I notice lean sneezes during transition to high speed. 2-6k performance is always PERFECT! I have even drilled a set of idle jets and then leaned mixture screws for compensation in hopes obstruction would not occur without success.
Quite possibly the most informative video I have ever watched on here! Helps me a lot with my smaller outboard. Cheers mate ! :)
+Christofer Cantley Thanks Christofer, glad you liked the vid. :)
Thank You very much Well Done ,Well Clear ,Calm, Excellent Presentation.
Glad it was helpful!
Thumbs up for sure as usual ✅👍 hope it helps others see your vids
So peaceful, clever and simplified.
Definitely feel like my man card is renewed with every vid. Thx brother
Thanks for another great video. I've got a 1998 force 90 hp on a project boat and I haven't touched a carb in 30 years. Runs good for about 10 minutes and then just stops (think it's likely a coil, or at least something in the ignition). First though, I wanted to refresh the fuel delivery by replacing all the fuel lines/clean carbs and rebuild the fuel pump, as the fuel filter was in worse shape than I've ever seen. Not much real cost to those activities so once that's all good and I'm confident in the fuel system, I'll get into the shut-off-when-warm issue.
Hey Jeremy, when I read your problem I first thought fuel and maybe overheating so I'm glad to hear you are running through the fuel system. It could be a fuel pump problem too if you prime the carburettor and then the motor stops when the float bowls get empty but they probably wouldn't last 10 minutes.
Thanks for the tip! I'm in no rush to get this one sorted, it's just a 'for fun' and stay busy project at this point. Re-priming the bulb doesn't have any impact which I thought made the fuel pump less likely. I'd guessed not a general overheating as the water stream is good, but it does start back up and run good after 10-15 minutes (for another 10 minutes until it repeats...) so it could be.
I learn so much from you and your videos, Thank You!
I would like to suggest as part of your videos that you show before and after performance of the motors
Great suggestion!
just to let you know , i finally got time to clean my carburetor, you were trouble shooting it with me all last week ; and the problem was the rubber hose that connects to the pickup and the other end to the carb , was sitting in the bottom of the bowl, i picked it up and it just crumbled apart . So since i had to carb apart i gave it a good cleaning put on a new hose and like what you said , It was a great feeling having that motor purring again. Thanks again for all your advice and i am going FISHING NOW!!!
GmGarlo Enjoy your fishing! :) I had a similar problem with the Green Machine yesterday when it wouldn't start (dead ignition relay), but then it wouldn't start either when I hot wired it. Pumped the bulb and fuel shot out the side because the port on the fuel pump had snapped right off! :O
Great vid Stu.A point on the yammy 2st I found was that they govern idle speed in neutral, so if your are only getting 1/2 throttle after putting linkages back on, Select forward and check for full advance and full throttle. Had me stumped for a few minutes thinking a throttle linkage was jamming on something.
Cheers
Matt
Hey Matt, good tip about the linkages. They are all a bit different and it can take a bit to get your head around how they are designed to work some times.
This is true for all outboards, I would assume, otherwise it'd be like leaving your car in neutral and just holding the pedal to the floor. Even worse for 2-strokes, as no valve train to float and keep engine from overrevving (and destroying itself).
RichE
Yeah good point. I reckon some of those small hp 5's etc, can rev at WOT in neutral the way some people start them and rev them.
Muchos gracias senor I clean the carburetors I'm going to start it up tomorrow thank you
Good luck! :)
Great Content. So helpful to the boating community, worldwide.
Thanks mate, my pleasure!
Hey mate! Saw you on SV seekers channel a while back, and just came across this video due to my 4hp mariner not starting, looks to be a very similar carb. Thanks for the very informative video, gonna give it a go and hopefully this sucker will crank up!
You’re welcome. Good luck!
Tnx!!!! Very good video, greats from Norway!
Отличное видео, Спасибо!!
Great video, thanks!!
Wonderful! Thx
I love your videos, I’ve learned a lot thanks to you! 👍🙏🍺🤝😌
Thanks
Great video. Good job. Informative and enjoyable to watch
Glad you enjoyed it!
Hi mate great video ,thankyou very much for the great advice. What yamaha year/ model did you work on ? Thanks again
Niiice video..thanks for sharing your experience.
You're welcome. :)
Thanks mate 👍
Hey Dangarstu,
Your videos are very instructive. How about doing one on adjusting the carburetors of an outboard such as a three cylinder 2 stroke.
Thanks Bob, I sure will. My Yamaha is a four carb model and I have some vacuum gauges that just need a new valve. I'm away on holidays at the moment so no vids until I get back but I'll do that one sooner rather than later.
Have a look at ruclips.net/video/bsHCMJnRY9A/видео.html
Top video mate, really simple and easy to follow.any chance you can do a video of the correct outboard for a boat. ( as in short shaft or long shaft) please
Have a 98 15 hp Yamaha 4 stroke that has the same carb. Your video will help me a lot. Yesterday the motor would run fine at half throttle and when going to full throttle it would initially speed up but then began losing power. I backed off throttle and would idle fine. Run at half throttle, but going to full throttle the engine did not respond. Going to give the carb a clean using your video and see what happens. Thanks for your videos.
Hi David. A carb clean is probably a good idea, but I would also be looking for fuel supply problems. ie, check the fuel lines for kinks or crack, make sure the breather is open on the fuel tank, make sure the fuel pump is good when you do the carb clean.
Dangar Marine Stu, thanks for reply. Well I took out for another test run after carb clean and initially ran fine but after about 7-8 min engine started losing power at wot. Engine also hot. Pulled thermostat and stuck closed. Engine overheating causing power loss. Hope I haven't destroyed engine. Any idea why temp sensor did not activate. I can't even find the sensor. Any ideas where the sensor is? Never mind Stu. Found out from Yamaha that y motor has no temp. Alarm
Love your videos. Very informative. I'm ready to try this on my carbs. How about a video on sync'ing carbs?
Thanks mate. Will be doing a carb synching video very soon. Stay tuned!
Hot tip for cleaning carbs. Probably more suited to carbs that are dirtier than the one in this vid, use a bamboo skewer with a sharpened tip to gently probe and ream jets, galleries and apertures. Then carry on with the carb cleaner/compressed air routine to clear any tiny fibres that may get left behind. The blunt end of the skewer also works well to gently scrub delicate brass parts such as the dirty tip of your idle screw needle without risking abrading or scratching the surfaces.
